Phenom II X2 N620 is a Dual core mobile CPU based on the Champlain Core and therefore related to the Athlon II X2 Desktop Series.
It features 2 cores, clocked 2.8GHz and the fastest supported memory is DDR3-1333.
Its performance is just average but decent enough to run most games from medium to high settings fluently, if paired with the appropriate GPU, obviously. However, the most demanding games will require reduced settings to be played optimally.
